retribution ship how can i get that cause i miss it i never got a chance to get the ship from campain

It is currently available in the Bounty store for 1700 points. You get 800 points for joining, and 800 more every 6 hours if you are on to collect it.

If you joined, waited for the first bounty grant, and then had a friend send a Gunboat against your base a couple times you would secure the first checkpoint of the day for 2000 points and have enough safe points to redeem it when the store opens.

The alternative would be to join towards the end, and see if someone could prep you a Bandit Base or two. You should receive the last 800 points when Bounty ends as well.
